A thought so fragile

Someone said “She is in town”,
His happiness had no bound,
The anticipation to meet her after a few years,
Left a smile and also brought tears,
The days passed and the time had come,
To meet his beloved one,
His eyes were dying to catch her sight,
He wanted to hug her so tight,
There were lots of things he planned to tell,
His experience of life as a heaven and hell,

His memories took him four years back,
When she was vulnerable and had fears,
She wanted a shoulder and someone to hear,
And he was there to hold and care,

And then he saw her standing a little away,
Their eyes met but she looked away,
He walked to her and said "hi",
She nodded back and as if she meant “bye”
There was a feeling that she was not at ease,
All words which he never said,
Were running in his head,
He said sorry and shook her hand,
He didn’t dare to hug her or even stand,
Turned back ……good bye with smile,
Just with a question….
Why is her thought so fragile?
